Study information

Primary study design	Interventional
Study design	Randomized; Both; Design type: Prevention, Dietary, Management of Care, Qualitative
Secondary study design	Randomised controlled trial
Study type	Participant information sheet
Scientific title	Adults undergoing major lung surgery randomised to nutritional intervention or equivalent volume in water to assess the effects on post-operative outcomes
Study acronym	ThIRStY
Study objectives	The aim of this study is to assess the feasibility of carrying out a randomised controlled trial comparing the effectiveness of a nutritional intervention (NI) of preoperative carbohydrate-loading drinks and early postoperative nutritional supplement drinks compared to receiving an equivalent volume of water in enhancing recovery after major lung surgery (MLS)
Ethics approval(s)	Wales REC 7, 05/09/2016, ref: 16/WA/0254
Health condition(s) or problem(s) studied	Specialty: Cancer, Primary sub-specialty: Lung Cancer; UKCRC code/ Disease: Cancer/ Malignant neoplasms of respiratory and intrathoracic organs
Intervention	After written informed consent, the patient will be randomised, before surgery, to either a nutritional intervention or water. Participants will be individually randomised into the study in an equal 1:1 ratio. Randomisation will be by a web based randomisation system. Patients will be stratified by diagnosis (cancer or benign) and type of surgery (key hole or open). The nutritional intervention in brief the evening before surgery 4x200mls, the morning of surgery, 2X200mls of carbohydrate-loading supplement will be given. In the postoperative period patients will be given 125ml polymeric nutritional supplement drink twice a day from the period immediately after their operation for 2 weeks. The control group will consume the same quantity of water thus any benefit from the intervention will not be due to preventing dehydration. Follow up will be 3 months post-surgery with Visual Analogue Score (VAS), Quality of Recovery and EQ5D questionnaires.
Intervention type	Other
Primary outcome measure(s)	Recruitment rate is recorded as the number of eligible participant who consent to participate in the study by 12 months.
Key secondary outcome measure(s)	1. Reasons for failure to recruit are assessed by screening log at the end of the study 2. Ease and efficiency of randomisation process is assessed by speed in which patients can be randomised and whether important prognostic data can be collected pre-operatively at the end of the study 3. Compliance rate of the intervention and contamination rate of the control group is assessed by data gathered by questionnaire and interview, we would expect to have a compliance of 50% of prescribed carbohydrate drinks and ONS taken as scheduled by the end of recruitment 4. Robustness of data collection processes during patient’s hospital stay is assessed by completeness of important peri-operative data to be over 90% for each patient. 5. Follow-up rate of patients at 3 months is assessed by a response rate of 80% at 3 months 6. Reasons for loss of follow-up (if any) are measured at 3 months,100% of mortality data will be captured. 7. Questionnaire best reflects patient experience is assessed by patient interviews at 3-4 week post-surgery. 8. Variability and distribution of quality of life questionnaires measured by return rate up to 3 months after surgery
